Mineral wool, also known as rock wool or stone wool, is an insulation material made from natural or recycled stone or basalt. The process involves melting the stones at high temperatures and then spinning them into fibers. These fibers are then processed into various forms, including batts, blankets, and boards. Mineral wool is highly regarded for its impressive thermal and acoustic insulation properties, as well as its resistance to fire and moisture.
The primary component of rigid mineral wool board is basalt, a natural volcanic material, which gives it its distinct insulating properties. During manufacturing, basalt is melted at high temperatures and then spun into fibers, which are subsequently compressed and formed into rigid boards. This process results in a dense, robust product that exhibits low thermal conductivity, making it an effective insulator.
